ZGQ-10 Lightning Counter
General 
ZGQ-10 lightning counter is used to record the number and the time of lightning strikes. Applying the principle of current induction and displaying by three-digit digital tube, it can record the lightning current with amplitude in the range of 1.5 kA to 100 kA.

Working Principle                                                                             
The inductance probe is installed on the wire (generally the ground wire) through which the lightning current passes. When the lightning current comes, the inductance probe collects the lightning current signal and converts it into the voltage signal. After signal processing, the voltage signal is sent to the display unit controlled by the single-chip microcomputer. One record of lightning current is generated. When the lightning current comes again, record the lightning current again until 999 times then reset.
